ELENA finishes Commissioning
ELENA, a new ring that will slow the Antiproton Decelerator’s antiprotons down even further has now finished construction and is entering the commissioning phase. Read about it here and check out the timelapse video of the construction below. For more information, read the CERN Courier article or visit the ELENA project website. We're looking forward

Canadian Members of ALPHA win NSERC John C. Polanyi Award
Members of the ALPHA Collaboration from Canada were recently awarded the NSERC John C. Polanyi Award for their contributions to ALPHA’s sucesses in trapping and measuring antihydrogen atoms. The award honours an individual or team whose Canadian-based research has led to a recent outstanding advance in the natural sciences or engineering. The Canadian group contributes

ALPHA probes Antimatter Gravity
Physicists have long wondered if the gravitational interaction between antimatter and matter might be different than that between matter and itself. Do atoms made of antimatter, like antihydrogen, fall at a different rate to those made of matter, or might they even fall up – antigravity? There are many arguments that make the case that

ALPHA 2 arrives at CERN
Right now everyone at ALPHA is busy assembly the ALPHA 2 apparatus, the sucessor to ALPHA. The most recent parts to arrive have been the atom-trap cryostat built in TRIUMF in Vancouver, and the new superconducting solenoid, built by Oxford Instruments in the UK and financed by the Danish Carlsberg Foundation. They join the catching

First Antiprotons caught in ALPHA 2
The first antiprotons were caught last night in the new ALPHA 2 catching trap, the first component of the next generation of the ALPHA experiment to be installed. This is the representation of the first 'hot dump' — where we release the captured antiprotons, allowing them to annihilate on the surrounding apparatus. The annihilation converts

A new result from ALPHA – The first measurements of the Antihydrogen Spectrum
Once you've trapped antihydrogen what do you do? You measure it! That’s just what we’ve done. Published in Nature, we report the first resonant quantum transitions in antihydrogen atoms. We’ve used microwave radiation to change the internal state of the atom, from one which can be kept in our trap, to one that is kicked

New ALPHA Octupole being wound at BNL
Our new octupole is being made at Brookhaven National Laboratory – here’s a video that they’ve sent us of the work in progress. The superconducting wire is laid down by a machine-controlled head, and bonded in place as it goes. The new octupole will be welded into the ALPHA 2 cryostat and commissioned at CERN
